【正文】 II Abstract With the growing of modern science and technology development, application of the screw conveyor is more and more widely. When the material was added to the inlet orifice, and the shaft rotated, the materials was given the thrust by the helicallobe. The thrust of the radial contribute to the material and blade the friction, it is possible that the materials could rotate around the axis, but because of the gravity of the material and the friction which the silo acted, the material do not rotate with the helicallobe, it move along the axis of the silo by the thrust of the spiral blade . For the construction industry background, which is required by the screw conveyor design and structure in this design. The entire device in the transmission system for the movement of mechanical and structural was designed. The design of its driving system and the specific design of its main parts, which is including the screw conveyor spiral diameter, pitch, the shaft diameter of inlet orifice, the calculation and selection of the shafts, the middle hoist and the spiral axis were carried out. In detal, motor is through the power of the screw conveyor to calculate and select. The gears in the reducer is calculated by the gear surface contact fatigue strength and checked by the gear bottom bend fatigue strength, I check the diameter of axle through the permissible bending stress Keywords motor reducer helicallobe spiral axis I 目 錄 1 緒論 ............................................................................................................................................. 1 螺旋輸送機(jī)產(chǎn)品概述 .......................................................................................................... 1 螺旋輸送機(jī)應(yīng)用范圍 .......................................................................................................... 1 螺旋輸送機(jī)主要特點(diǎn) .......................................................................................................... 2 螺旋輸送機(jī)工作原理 .......................................................................................................... 2 螺旋輸送機(jī)整機(jī)布置形式 .................................................................................................. 2 1. 6 螺旋輸送機(jī)規(guī)格 、 技術(shù)參數(shù) .............................................................................................. 6 ..................................................................................................................... 9 電動(dòng)機(jī)的選擇 ...................................................................................................................... 9 傳動(dòng)裝置的運(yùn)動(dòng) 和動(dòng)力參數(shù)的計(jì)算 ................................................................................ 10 ....................................................................................................................... 13 齒輪設(shè)計(jì) ............................................................................................................................ 13 減速器結(jié)構(gòu)設(shè)計(jì) ................................................................................................................ 19 軸設(shè)計(jì) ................................................................................................................................ 20 軸承的選型 ........................................................................................................................ 25 鍵的選型 ............................................................................................................................ 26 ........................................................................................................... 30 機(jī)體主要部件的介紹 ........................................................................................................ 30 機(jī)體主要部件的選擇計(jì)算 ................................................................................................ 39 體的安裝條件、使用及維護(hù) ........................................................................... 45 螺旋輸送機(jī)機(jī)體的安裝條件 ............................................................................................ 45 螺旋輸送機(jī)機(jī)體的使用及維護(hù) ........................................................................................ 47 結(jié)論 ............................................................................................................................................... 49 致謝 ............................................................................................................................................... 50 參考文獻(xiàn) ....................................................................................................................................... 51 附錄 ............................................................................................................................................... 52 附錄一 ........................................................................................................................................ 52 英文資料 ................................................................................................................................. 52 中文翻譯 ................................................................................................................................. 58 1 1 緒論 螺旋輸送機(jī) 產(chǎn)品概述 螺旋輸送機(jī)俗稱絞龍， LS 型系列螺旋輸送機(jī)是一種利用螺旋葉片的旋轉(zhuǎn) ,推動(dòng)散料延著料槽向前運(yùn)動(dòng)的輸送設(shè) 備 ,適宜于輸送粉狀 ,顆粒狀和小塊物料。 LS 型螺旋輸送機(jī)與 GX 型相比，其頭部、尾部軸承移至殼體外，出料端設(shè)有清掃裝置，整機(jī)噪聲低，適應(yīng)性強(qiáng)，操作維修方 便。 3. 整機(jī)體積小、轉(zhuǎn)速高、確?？焖倬鶆蜉斔?。螺旋面的形式有實(shí)體螺旋（ S 制法）和帶式螺旋（ D 制法）兩種。頭節(jié)前部裝有止推軸承。 生產(chǎn)單位一般用三 相交流電源，因此，如無(wú)特殊要求都應(yīng)選用交流電動(dòng)機(jī)。 電動(dòng)機(jī)類型要根據(jù)電源種類（交流或直流），工作條件（溫度、環(huán)境、空間位置尺寸等），載荷特點(diǎn)（變化性質(zhì)、大小和過(guò)載情況），起動(dòng)性能和起動(dòng)、制動(dòng)、反轉(zhuǎn)的頻繁程度，轉(zhuǎn)速高低和調(diào)速性能要求等條件來(lái)確定。根據(jù)以上兩點(diǎn)和機(jī)械設(shè)計(jì)手冊(cè)，選用 Y132M4 型號(hào)的電動(dòng)機(jī)。 η 齒輪 = = 主軸 3P = 2P i m 2 軸 2T? = 2T 設(shè)計(jì)的該螺旋輸送機(jī)的預(yù)期使用壽命 10 年，每年 300 個(gè)工作日，在使用期限內(nèi)，工作時(shí)間占 20%。因此 ,機(jī)體結(jié)構(gòu)對(duì)減速器的工作性能 ,加工工藝 ,材料消耗 ,重量及成本等有很大的影響。 = 軸向力
